A microstrip antenna radiates and receives six beams in sequence out of a common aperture and processes return signals with common electronics in order to measure the velocity components relating to a backscattering surface. Sequentially, the first four beams are processed by measuring Doppler shift in a return signal while the last two beams are processed for time correlation. The result of the present invention is a combined time correlation and Doppler measurement velocity sensor available for operation over virtually all terrains and the vehicle speed range.

Radar multibeam velocity sensor

Accurate vehicle pitch and roll can be computed from a corresponding signal loop which receives inertial data input contaminated by the effects of gravity on a vehicle. Data from Doppler radar is compared to the inertial data and an error signal dependent on pitch or roll angle is substracted from the input inertial data resulting in the generation of accurate navigational parameters.
